Panasonic — Refrigerator service delay

Refrigerator purchased in January 2022. On 3rd during a voltage fluctuation it stopped working. Registered a complaint on 4th September and was promptly attended by the technician on 5th September. He said card failure and card to be replaced. Till date not replaced. On enquiry it was informed that order placed and will be coming from Chennai. But due to delay, called and the person responsible told that it will take around a weeks time additionally as it has to come from Delhi. 2 weeks without Refrigerator is a lot of time and difficult to manage. Who will take responsibility for this delay?
